btrfs: simplify extracting delayed node at btrfs_first_delayed_node()

Browse source

Instead of grabbing the next pointer from the list and then doing a
list_entry() call, we can simply use list_first_entry(), removing the need
for list_head variable.

Also there's no need to check if the list is empty before attempting to
extract the first element, we can use list_first_entry_or_null(), removing
the need for a special if statement and the 'out' label.
